Re: [Ltib] gdb built by ltib

[Stuart Hughes]

Hi Henry,

When you build gdb in LTIB, there are 3 selections you can make:

        [*] gdb
        [*]   gdb to run natively on the target
        [*]   cross gdb (runs on build machine)
        [*]   gdbserver to run natively on the target

The <top>/bin/gdb is the 'cross gdb' this is normally used in
conjunction with 'gdbserver'.  The idea of it is that some platforms
don't have enough resource (storage space and|or memory) to support a
full gdb on the target, so in this case you use the lightweight
gdbserver on the target and connect to it with a 'cross gdb' run on the
build machine.

The <top>/rootfs/usr/bin/gdb is full gdb that can run on the target
without support from the host.

Regards, Stuart
